	* sunrpc/xdr_mem.c (xdrmem_setpos): Don't compare addresses
	as signed longs, check for x_base + pos overflow.
	* sunrpc/Makefile (tests): Add tst-xdrmem2.
	* sunrpc/tst-xdrmem2.c: New test.

	* elf/dl-runtime.c: Include sysdep-cancel.h.
	(_dl_fixup, _dl_profile_fixup): Use __rtld_mrlock_* and

	instead of catomic_* macros.
	* elf/dl-sym.c: Include sysdep-cancel.h.
	(do_sym): Use __rtld_mrlock_* and scoperec->nusers only
	if !SINGLE_THREAD_P.  Use atomic_* instead of catomic_* macros.

	(_dl_close): Use __rtld_mrlock_* and scoperec->nusers only
	if !SINGLE_THREAD_P.  Use atomic_* instead of catomic_* macros.
	* elf/dl-open.c: Include sysdep-cancel.h.
	(dl_open_worker): Use __rtld_mrlock_* and scoperec->nusers only
	if !SINGLE_THREAD_P.  Use atomic_* instead of catomic_* macros.

	[BZ #3313]
	* malloc/malloc.c (malloc_consolidate): Set maxfb to address of last
	fastbin rather than end of fastbin array.

2006-10-18  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/i386/i486/bits/atomic.h (catomic_decrement): Use correct
	body macro.
	* sysdeps/x86_64/bits/atomic.h
	(__arch_c_compare_and_exchange_val_64_acq): Add missing casts.
	(catomic_decrement): Use correct body macro.
